JASON D. SIMMONS, OF' CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO MARY L. SIMMONS, OF SAME PLACE.

SASH-SUPPORTER.

SPECIFICATION forming part of Letters Patent No. 314,201, dated March 1'7, 1885. A pplication filed April 1-1, 1884. (No model.)

I To all whom it may concern:

Be it known that I, JAsoN D. SIMMoNs, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sash-Supporters; and I do hereby declare that the followingis a full,clear, and exact descriptionthcreof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form partof this'specification.

This invention relates to supporters for window-sashes; and it consistsin certainimprovements on the device patented to me on the 12th day of February, 1867, No. 62,078, the object of said improvements being to provide a device which shall admit of the complete raising and retention at the highest point of the upper sash, and which shall possess superior advantages in point of simplicity, durability, and general efficiency over other devices of this class.

My invention consists in a detent of peculiar construction to be used in connection with the other parts of the device, as more particularly pointed out in the claim.

In the drawings, Figure l is a vertical section taken through one side of the upper sash and the adjacent part of the window-frame. Fig. 2 is a similar view through the lower sash. Fig. 3 is a perspective view of the frame of the supporter; and Figs. 4 and 5 are detail views.

The same letters refer to the same parts ,in all the figures.

In order to fully show the operation of my invention I have shown the same in connection with the usual levers and attachments employed in this class of sash-fasteners, to which, however, I make no claim.

A designates the supporter-frame, which consists of a plate having flanges B B, provided near their upper ends with ears 0 0, between which is pivoted an eccentric lever, D, the face of which has a tooth or lug, E. The lever D is provided with two downwardextending arms, F and G, between which ex- ,tends a spring, H, secured to the lower end of plate A.

In practice the side of the sash to which the device is attached is provided with a recess, I, in which it is seated and secured by screws or other fastenings inserted through openings at the upper and lower ends of plate A. The

projecting eccentric port-ion of the lever D is, by contact with the side of the window-frame, forced back into the casing against the tension of spring H, which, by pressing against the arm F, forces the lug E againstthe window-frame with sufficient force to letthe camwedges sustain the sash at any elevation. The arm G forms a guard for the upper end of the spring.

Into the side of the window-frame. near the upper end of the same, is driven or otherwise secured a triangular plate or plates, 1, the

faces of which have notches J, which will engage the wedge E, thus sustaining the sash and preventing it from sinking when raised to its desired height.

To raise the sash it is only necessary topnsh it upward,which may be done with the hands,

or, in case of high windows, with a pole.

To lower the sash the projecting end or handle oflever D is raised, thus withdrawing the wedge E into the casing and permitting the sash to drop.

The spring H of the device attached to the lower sash has a pin or stud, K, which may project through an opening, L, in plate A. When this sash is entirely lowered, this pin registers with an opening, M, in a plate, N, which is secured in the side of the window frame, and is provided with a recess, 0, to receive the eccentric portion of lever D. \Vhen the sash is lowered, the spring II will force the eccentric or cam-wedge portion of the lever D into recess 0, causing stud K to enter the opening M and lock the sash. To raise the sash from this position it is necessary first to raise the handle of the lever so as to release the locking device; but this being clear of the plate N it may be manipulated like the upper sash.

Having described my invention, I claim Asa new article of manufacture, the detent, consisting of an angular plate adapted to be driven into the sash and having a segmental serrated edge adapted to engage and hold the ICQ
